A suspected Islamic State supporter encouraged lone wolf attackers to target Prince George at his school and to poison ice creams, a court has heard.

Husnain Rashid posted a photo online of the four-year-old prince with the address of his Battersea school, a silhouette of a jihadist fighter and the message "even the Royal Family will not be left alone", a jury at Woolwich Crown Court heard.

The 32-year-old, who taught at the Muhammadi mosque, denies three counts of preparing terrorist acts, one count of encouraging terrorism, two of disseminating a terrorist publication and one of failing to comply with a notice under the Regulation of Investigatory Powers Act.

On the first day of his trial, jurors heard that the accused, from Nelson in Lancashire, provided an "e-toolkit for terrorism" in a "prolific" online Telegram channel he ran called the Lone Mujahid.

Prosecutor Annabel Darlow said: "His proposals were indiscriminate and made no distinction between adult and child, between members of fighting forces and civilians. His suggestions included injecting poison into supermarket ice creams and targeting Prince George at his first school." He is also accused of posting a photoraph of the Burmese ambassador to the UK which said: "You know what to do."
